To all whom it may concern:

Be it known that I, S'rnwAirr \VAIuNu, a citizen of the United States,residing at Evanston, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Apparatus for Trimmingand Marking all-Paper, of which the following is a specification.

WVall paper, as heretofore manufactured, has been provided with asclvage at each edge to protect the body of the paper from injury duringtransportation and handling. If the. paper was to be used with the edgesthe paper-hanger was obliged to trim off both selvages. If the paper wasto be hung with the edges of the lengths overlapped, the paper-hangertrimmed off one selvage, the other sclvage beingoverlapped by thetrimmed edge of the adjacent length of paper.

The object of this invention is to provide means for so treating wallpaper as to economize the time of the paper-hanger in hanging the paperwhether the paper is to be hung with edges abutting or overlapped. Thisobject I accomplish by trimming off one selvage and by placing along theother selvage a suitable gage mark, indication or line to indicate tothe paper-hanger the line along which the selvage should be trimmed oroverlapped.

In the accompanying drawings, Figure 1 is a fragmental top plan view ofa machine embodying the features of my invention. Fig. 2 is a sectionalview taken in the plane of dotted line 22 of Fig. 1. Fig. 3 is a viewlooking from the left-hand side of Fig. 1. Fig. 4 is a sectional viewtaken in the plane of dotted line 4-4 of Fig. 1. Fig. 5 is a section ondotted line 5-5 of Fig. 1.

While the before-mentioned trimming and marking may be effected at anydesired stage in the manufacture of the wall paper, these operations areconveniently performed in connection with the re-rolling of the paperinto rolls of the size in which the paper is to be marketed. In suchre-rolling operation any suitable mechanism may be used, as for example,that shown in Patents Nos.- 999,352 and 1,081,933, granted to me onAugust 1, 1911, and December 16. 1913. respectively. Herein I have shownpaper-guiding rolls 1, 2. 3 and 4 located adjacent to the mechanismshown in Patent No. 1,081,933, said rolls being rotated throughfrictional contact with the web of wall paper A passing around saidrolls.

The means for trimming off one selvage comprises a circular knife 5which is socured to a shaft (3. The shaft 6 is rotatably mounted inbearings 7 and 8. As shown in Figs. 1 and 2, the bearings 7 and 8 areattached to the supporting frame by means of thumb-screws 7 extendingthrough vertical slots 8 in the supporting frame, so that the shaft 6may be raised to remove the trimming and marking devices from contactwith the paper when desired. \Vhilc the shaft 6 may be driven in anysuitable manner, it is herein shown as continuously driven by a belt 9running over a pulley 10 on the shaft 6. The knife 5 is so located withreference to the paper that as the latter passes over the roll 2 theselvage A is severed from the body of the web.

The means for marking the opposite margin of the web to indicate to thepaperhanger where the selvage should be trimmed off or overlappedcomprises a marking disk 11 which is fixed upon the shaft 6. Theperiphery of the disk 13 runs in contact with the web A.

Any suitable means may place a marking of the disk 11.

be employed to fluid upon the periphery Herein is shown an ink reservoir12 in which is rotatably mounted a roll 13. Above the roll 13 is a roll14. An ink-carrying tape or belt 15 runs over the rolls 13 and 14 and incontact with the periphery of the disk 11. The roll 13 is driven bymeans of a belt 16 running over sheaves 17 and 18 fixed respectively onthe shaft 6 and the shaft of the roll 13. A scraper blade 1.) supportedadjacent to the ascending side of the tape 15 removes surplus ink.

The paper is fed to the rolling machine intermittently, the feed of thepaper being suspended while the web is being severed by the shearassociated with the rolling mechanism. In the present embodiment thetrim ming knife 5 and the marking disk 11 rotate continuously. If theroller 2 were allowed to rotate through momentum after the feeding ofthe web is stopped, said roller would cause the web to become more orless slack between the rolls 1 and 2. To prevent this result, I providea brake consisting of a shoe 20 arranged to engage a wheel 21 fixed tothe shaft of the roll 2. The shoe 20 is attached to a stem 22 which ismounted of the paper 1s "suspended.
